So earlier today I received a letter notification, it was red and blinking and from what I know that means a GM sent me a message.

I went to look in my Mog Mail and it said no unopened letters, so I looked in opened letters and that was empty too, where as it's usually got a few fantasia/vet rewards letter there.

Now I'm wondering if this can be fixed. Cuz if it can't it means I can no longer receive any letters, including Mog Station items.
